Description
Technical field
The utility model relates to a kind of gas circuit damping filter.
Background technology
In the fields such as metallurgy, chemical industry, building materials, electric power, usually to measure the parameter such as pressure, flow velocity, flow of gas circuit, under normal circumstances, because gas circuit airflow fluctuation is very large, cause measurement instrument to show very unstable, the data error cannot measuring gas path parameter or measurement is larger.Usually adopt software to carry out filtering process to the output of digital instrument at present, thus improve output stationarity, but digital instrument is expensive.CN 103512587A discloses a kind of gas circuit Fault detection filter, it cuts down the fluctuation amplitude of air-flow by the damping gentle cavity volume filtering double action increasing gas circuit, various surveying instrument is enable to export stable airflow signal, it is the size being regulated gas channel by screw, thus regulate gas circuit damping, the effect of this mode is still bad, or larger metrical error can be caused, and can not filter air-flow, when containing more solid impurity in air-flow, not only can strengthen metrical error, and detecting instrument below can be damaged.
Summary of the invention
The purpose of this utility model is for above-mentioned defect, provides a kind of gas circuit damping to regulate gas circuit damping filter more accurately, enables gas circuit surveying instrument export airflow signal more stably.
Above-mentioned purpose is achieved through the following technical solutions:
A kind of gas circuit damping filter, comprise the draft tube of airtight connection successively, air-capacitor pipe, escape pipe, the internal diameter of described air-capacitor pipe is greater than the internal diameter of draft tube and escape pipe, gas filtration film is provided with in described air-capacitor pipe, the aperture of described gas filtration film is 0.15 ~ 0.6 μm, and thickness is 0.3 ~ 1.5mm.
Described air-capacitor pipe is made up of inlet end air-capacitor pipe and outlet side air-capacitor pipe two parts, and described inlet end air-capacitor pipe is connected with outlet side air-capacitor pipe hermetic seal.
The inside of described outlet side air-capacitor pipe is provided with jump ring, and the edge of described gas filtration film is fixed on jump ring, is provided with O-ring seal between described gas filtration film and outlet side air-capacitor pipe.
Described draft tube is provided with draw-in groove.
Described draft tube is provided with the boss for preventing draft tube from coming off from the pipeline connected and leaking gas.
Gas filtration film in the utility model can not only impurity in filtered air, the resistance of air-flow can be increased simultaneously, make the air-flow entering escape pipe become steady, in air-capacitor pipe, larger-diameter air-capacitor chamber is played the spike of filtering airflow fluctuation and cuts down airflow fluctuation amplitude.In the utility model, the aperture of gas filtration film and thickness are the keys regulating air-flow damping size, and the aperture of film is too little, and thickness is too large, and damping can be caused excessive, and load capacity consumes too much in damping, cause the flow upper limit detected not reach; Otherwise the too small meeting of damping causes air-flow not steady, affects testing result.Therefore, the size of damping should meet the accuracy and stability that detect flux lower limit, makes the flow upper limit have the load capacity met the demands again.It is for the ease of dismounting, replacing gas filtration film that air-capacitor pipe forms by two sections, reduces the effect of damping adjusting after preventing filtering membrane adsorbing too much impurity.The utility model can regulate gas circuit damping more exactly, makes the data of output more stable, reduces the error detected, can be widely used in the measurement of the flue gas pressure in the fields such as metallurgy, chemical industry, building materials, electric power, flow velocity, flow.
